My invention relates to improvements in copper and steel plate printing machines, and consists of novel automatically operating wipers for the same.

It further consists of the combination of parts as hereinafter described.

Fig. 17 represents an end view of the rollers for unwinding and winding the web on its rollers, and Figs. 18 and 19 represent views at right angles to each other of a wiper with moistening device. Fig. 20 consists of two sheets of drawings, one half of the machine on each sheet, and illustrates a partial side elevation and partial longitudinal vertical section of the machine.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings:-A designates a frame having journaled therein an impression cylinder B of the usual construction, and provided with a feed table 0 and a carriage or bed D, the latter movable in ways on the frame A, and adapted to support a plate from which the printing is done.

The mechanism for operating the carriage D is of any usual construction, and not being claimed herein is not shown nor described.

E designates an inkingtable, F an ink distributer, G distributing rollers, and H an inking roller, each of said parts being of any usual and well known form of construction.

The wipers J, J, and J are identical in construction, except as hereinafter set forth and a description of the parts of one and its operating gearing will be sufficient to fully explain all of the same.

Suitably supported above the carriage D, and in suitable bearings formed in arms K, K, and K are the vertical shafts L, L and L of which the shafts L and L receive rotary motion by means of the pulleys M, M thereon connected by belts, N N with pulleys M M mounted on the shafts N, N',having the wheels P, P, in frictional contact with wheels Q, Q, mounted on a rotary shaft R journaled on the frame A. The wiper J has simply rising and falling motion, its shaft L having no rotary motion. Secured to the lower end of the shaft L, which is adapted to rise and fall in its bearings isa frame or cage S in which isjournaled a horizontal shaft W having mounted thereon the two levers or arms T, T supporting at their outer ends the rollers U, U, to which are secured the ends of the web JX of the wiper J, which passes around the tension rollers V, V, and g the cushion W. The said cushion W is connected with a block X, detachably secured to the bottom of the frame S, and the-said tension rollers V, V, have slotted hearings in the said frame, so that-the said'rollers may be separated and thereby permit the introduction between them of a new web. See Fig. 9. In Fig. '7 the journals of the said rollers are shownattheinnerendsoftheslots,thisposition being due to the strain of the web J thereon. The shaft L is raised and lowered by means of a lever Ymounted on the arm K, and connected atone end tosaid shaft by means of the studsZ fittedin acircumferential grooved collar A, which is secured to said shaft, said lever having at its other end a rising and falling rod B provided with an anti-frictional roller 0, which is in contact with a cam D" on the driving shaft E; A rock-shaft F journaled in the up'per walls of the frame S,

has an arm or lever O connected therewith,

the end of said lever-being adapted to come in contact with a collar H on the shaft L, whenthe sai'dshaft is lowered, and thereby oscillate the said rock shaft.

Depending fromthe rock-shaft F is a lever or arm Rhavingpivotally connected to its lower enda link S, which is also connected to one'limb of a bellcrank lever T mounted on the shaft W, suitablyjournaledin the frame :arm R and held against the said'forked end,

of the limb by the spring 0 is removed from contact therewith. A gear wheel Y secured on-said-shaft W is actuated by the movements of the said pawl X, so as to rotate said shaft and thereby the connected frictional -train .A, see Fig. 17, so that the web is slowly around said rollers V,'V, V, V, that their unwound from the roller U, and wound on the roller U. The said train A .is connected with the feedrollers V, V, whose journals are mounted in slots in the frame S.

V, V, designate pressure rollers freely mounted and rotatable onshafts journaled in slots in said frame. The web 'J is so passed shafts. occupy adjacent ends of their respectiveslots-and eachset V, V, of the rollers holds the web tightly between it so that when the rollers V,'V, are rotated by means of the' train A rotary motion is also imparted tothe rollers V, V, and the web is advanced be tween the rollers V and V. To further insure the pressure of the rollers V, V, against roller V to occupy the end of the slot in which it has a bearing, adjacent to the roller V. See Fig. 7.

In Fig. 9, the arm 13 is shown free from the spring and the shaft of the roller Vis shown in the end of the slot farthest from the roller V, in which position the web is not advanced or fed from one roller U to the other roller U. The-shaft of the roller V is moved by hand by means of the arms B when the said arms are released from the springs C. The ends of the springs G are threaded, freely passing throughopenings intheir supports, and areprovided with nuts D for securing them in place; A spring D secured atone end .to the frame S, and at the other to the end of a lever E attached to the shaftF returns the levers S, T, to their original positionswhen the movement is completed. A

pin -15 in the frame S limits the play of said shaft 'by being in thepath of travel of'an arm E thereon.

Connected with an arm F depcndingfrom an oscillating box or collar G on the shaft W of the levers T, T, is aspring knuckle joint H for insuring the throw of the said oscillating levers T, T. The cushion At around which passes theweb inconnection with the wiper J is moistened by'water :from. a pipe B leading from a trough O suitably supported so as to keepthe. said web properly moistened. 1

The operating mechanism of the wipers J and J is timed so as to rise whenthe carriage D leaves the impression cylinder, and lower when the carriage approaches or .returns toward the same. On the carriage'D is atable P for carryingthe engraved platefrom which the printing isto bedone. T0 impartintermittent rotary. motion to the said tableP the same is mounted on a rotary shaft Q suitably supported in the said carriage. and carries a bevel gearwheel S meshing with a bevel gear wheel T on-a shaft U whichlatter is journaled in a depending attachment T of the carriage, and is rotated during a portion of the movement of the carriages by reason of the contact ofa pinion V? thereon with a rack W on the frame A of the machine. The bevel gear wheel T is loosely mounted on the shaft U and is connected so as to rotate therewith at the proper time, by means of the clutch X operatedhy the lever Y which latter is pivoted to the attachment T at one end and provided with an antifrictional roller Z at its other .end, the said roller being heldin contact with a 'camA on ashaft B operated from the driving shaft of the machine, by means of the spring 0 which is attached to the said lever Y and the attachment T A loop D connected w1th the lever Y and provided with a tooth or stud E engages the pins F stud E adapted to be inserted between the studs or pins F on a disk G on the shaft Q serves to arrest the rotation of the table P on its arrival at its normal position, and also insures the proper position of the table when it comes to rest. The clutch X is released from the bevel gear wheels 'I at the time the The parts are so timed that the clutch X is engaged with the bevel wheel T on the passage of the table under the wipers J and J, during the return movement of the carriage. During the rest of the time, that is, during the whole forward movement of the carriage, and on its return along the spaces outside of the wipers J and J, the table is not rotated. The operation of the carriage is the same as in machines of a similar character, and forming no part per se of this invention, need not be further described herein.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
